View Full Version : Engine/transmission controls
33 Hotrod with LS3 and 4l70e. I need advice on where to place harnesses and controls for the engine and transmission. I have the A/C installed and there is very little room left under the dash. Someone who has done this would be helpful. These need to be placed so access is available if needed in the future. If anyone has done this I would appreciate their experience.

I am actually in the middle of this exact install right now. I mounted the chassis fuse box to the left of the pedal box 83327 and the ECM to the right between the pedal box and the a/c. 83328 I am in the process of mounting the engine fuse box below the ECM. This will allow me to access the fuses and relays from under the dash. I will mount the transmission controller between the trans tunnel and the console, with the laptop connector in the console box. I will try to post some more pictures tomorrow.

I look forward to seeing them.

I apologize for the delay. I had company all weekend but I did get to finish the install of the ECM and fuse boxes. 834168341783418834198342083421 I built a hinged compartment between the engine computer and the engine fuse block. I will make a lot of the harness connections inside there.
Good ideas. I moved the chassis fuses left of the pedal box and positioned the ECM similar to yours. My a/c unit is different than yours as the ducting comes out the top. so I had to mount it so the harnesses exit to the rear. Thanks for the help. Also where did you mount your a/c drier?

I have not mounted the drier yet, but I am looking at low on the frame rail on the passenger side.
